Delta Took $8.2 Billion From a Credit Card Company Last Year. It Booked $3.4 Billion of It as Revenue.

Delta's annual report, filed with the Securities and Exchange Commission in February, contains a sentence that describes the modern airline more precisely than any route map. In 2025, earnings from American Express totaled $8.2 billion, which the company expects to grow to $10 billion over the next few years.

In the same reporting period, Delta's fourth-quarter earnings release put full-year loyalty revenue at $3.362 billion, up six percent. The $4.8 billion difference between cash collected and revenue recognized is the mileage liability, sitting on the balance sheet until members redeem. Delta reported roughly 35 million award tickets issued in 2025, accounting for twelve percent of revenue miles flown.

American's filing tells a version of the same story. Cash payments from co-branded credit card and other partners were $6.2 billion and $6.1 billion during 2025 and 2024. Against full-year revenue of $54.6 billion, bank payments supplied better than one dollar in nine. United, which flew 10.9 million MileagePlus flight awards in 2025, representing about 10.3 percent of its revenue passenger miles, does not break out MileagePlus revenue in its 10-K at all. That absence is itself informative.

John Breyault, vice president of public policy at the National Consumers League, gave Reuters in March the line that fits the filings.

"The modern airline is a gigantic rewards program that just happens to fly airplanes"

Status Now Costs Dollars, Not Distance

Follow the money through to the qualification rules and the design becomes legible. Delta's own page for earning 2027 Medallion status lists four thresholds and one currency: Silver at $5,000, Gold at $10,000, Platinum at $15,000 and Diamond at $28,000 in Medallion Qualification Dollars earned across the 2026 calendar year. There is no mileage path. There is no segment path. Distance flown has been removed from the formula rather than merely de-emphasised.

JetBlue arrives at the same place from the opposite end of the market. Mosaic tiers require 50, 100, 150 and 250 tiles, and a tile is earned per $100 of qualifying spend, which makes the four tiers $5,000, $10,000, $15,000 and $25,000. No distance component exists anywhere in the structure.

Alaska rebranded Mileage Plan as Atmos Rewards on 21 January 2026, setting tiers at 20,000, 40,000, 80,000 and 135,000 Status Points. For travel on or after 1 August 2026, Saver fares earn zero Atmos Rewards points and zero Status Points, where they previously earned thirty percent of miles flown. The partner award booking fee rose from $12.50 to $20 per person each way on 1 July, and the phone booking fee doubled to $30 the following day.

American is the counterweight, and an honest account has to include it. The airline announced on 7 January 2026 that it was maintaining AAdvantage status and reward levels for a third consecutive year. Scott Long, the senior vice president who runs the program, framed it around the carrier's centenary and member trust. Three years of flat thresholds while competitors moved is a real data point, not a press release.

The Award Price Now Depends on Your Wallet

The clearest single break with how loyalty used to work arrived on 19 February 2026, when United announced changes effective 2 April. Co-brand cardholders receive at least ten percent off all United award flights, and cardholders who also hold Premier status receive at least fifteen percent. United's own worked example prices a 200,000-mile Polaris award at 170,000 for a Premier cardholder.

Two passengers on the same aircraft in the same cabin on the same day now pay different quantities of the same currency for the same seat, and the variable is which bank they hold a relationship with. Under the same announcement, a general member without a United card earns three miles per dollar, a United Club cardholder earns eleven, and a Premier 1K with that card earns seventeen. General members without a card earn nothing at all on Basic Economy tickets.

Andrew Nocella, United's chief commercial officer, summarised the intent without ornament, saying MileagePlus members can now earn more miles faster with a United card. Jay Sorensen, who runs IdeaWorksCompany and has measured these programs for two decades, framed the wider contest more sharply in October, writing that airlines invented loyalty programs, but banks have amplified them into multi-billion-dollar businesses, and putting the consumer question as whether you are loyal to the airline or to the bank.

What Awards Have Actually Done to Their Prices

Devaluation is easy to assert and harder to measure, which is why the IdeaWorks domestic reward study published on 13 March 2025 is worth more than the anecdotes. Across six carriers, Alaska, American, Delta, JetBlue, Southwest and United, reward seat prices rose an average of nearly 36 percent since 2019, against a Consumer Price Index increase of 24 percent across the same period. The range was 9 percent to 153 percent.

American was the exception, with reward prices down 21 percent since 2019, and it shared the lowest prices in the sample with Southwest. A study that produces a counter-result for one of its six subjects is more trustworthy than one that does not. Sorensen's own reading of the earlier survey work pointed at a different culprit than the award chart, noting that the accrual penalties placed on basic economy fares have a crushing effect on program value for everyday consumers.

Air Canada Proves a Published Chart Is Still Possible

Delta eliminated its award chart in 2015, and United does not publish one either, so the standard defence of dynamic pricing is that fixed charts are no longer operationally feasible at scale. Aeroplan is the counter-example sitting in plain view.

Air Canada publishes a downloadable flight rewards chart, currently dated June 2026, built on five zones and distance bands. Within North America the chart opens at 6,000 points in economy for trips under 500 miles and 15,000 in business. North America to Atlantic starts at 32,500 economy, 60,000 business and 90,000 first. The chart goes further than most carriers would dare, publishing median redemption figures drawn from actual member bookings alongside the starting rates. Alaska's Atmos Rewards likewise remains among the few programs with a published chart.

Transparency is not the same as stability. Air Canada devalued that chart effective 1 June 2026. Business class on North America to Atlantic routes between 4,001 and 6,000 miles moved from 70,000 to 75,000 points, the same band in first went from 100,000 to 120,000, and North America to Pacific business between 7,501 and 11,000 miles climbed from 87,500 to 102,500. The largest single increase took long-haul Atlantic first from 140,000 to 165,000.

A chart can be published in 2026, and publishing it guarantees nothing except that members can see exactly what was taken and when.

The Scale of the Gap Between US and Everywhere Else

On Point Loyalty published the fourth edition of its valuation study on 31 March 2026, modelling more than 170 airline programs across more than fifty variables to produce enterprise valuations of loyalty programs as standalone businesses. SkyMiles ranked first at $31.8 billion, with AAdvantage at $26.7 billion and MileagePlus at $25.3 billion.

The next tier is a different order of magnitude. IAG's Avios came fourth at $10.3 billion, followed by Southwest Rapid Rewards at $8.9 billion, Lufthansa's Miles and More at $8.7 billion, Flying Blue at $7.5 billion, Aeroplan at $7.4 billion, Qantas Frequent Flyer at $7.0 billion and Air China's PhoenixMiles at $5.9 billion. The three US majors together total roughly $83.8 billion, which exceeds the combined value of the next seven programs on earth. Evert de Boer, the study's managing partner, observed that the value loyalty programs can bring for airlines has never been greater.

What a Traveller Should Do With Any of This

Status is now a purchasing decision, so work out your annual airline spend and compare it against the thresholds rather than against your flight count; at Delta, Diamond is $28,000 and nothing else. If you fly a carrier more than a handful of times a year, the co-brand card has stopped being a rewards accessory and has become the mechanism that determines your earning rate and, at United, your redemption price. The gap between a general member and a card-holding Premier 1K is now three miles per dollar against seventeen.

Watch the fare class as closely as the fare. Alaska Saver fares earn nothing from August, and Basic Economy on United earns nothing without a card, which means the cheapest ticket can carry a real cost measured in forgone qualification. Readers pricing a trip end to end will find the same arithmetic in our guide to building a real fare after the fee disclosure rollback, and the same devaluation logic applied to cabin upgrades in our reporting on what happened to the complimentary premium economy upgrade.

Delta expects the Amex cheque to reach $10 billion. The qualification rules will keep moving toward whatever produces that number.
